Abstract

The situation following reflexion of a discontinuous plane shockwave from a coplanar, heat-conducting wall is analysed by the method of matched asymptotic expansions. Temperature jump effects are included. Two terms of the outer expansion are calculated ((i) the ‘ideal’ inviscid, nonheat conducting solution; (ii) the displacement effect) as well as two terms of the inner series ((i) constant pressure thermal boundary layer; (ii) first correction term resulting from pressure and temperature changes due to the displacement effect). The results agree reasonably well with experimental observations and it appears that accommodation effects may account for some observations of reflected-shock trajectories.
